HOSE-COUPLING.

Specification of Letters .Patent Patented Aug. 19,1913.

- Application ied November 7, 1911. Serial No. 658,950.

To all who-m 1' 1f may concern.'

Be it known that I, PAUL lV. LANGILLE, a subjectof the King' of Great Britain, residing at Lunenburg, in the Province of Nova Scotia and Dominion of Canada, have invented certain new and useful Improvements in Hose-Couplers, of which the fol lowingr is a specification.

This invention relates to an improvement in hose-couplings especially adapted for use in connection with locomotives although the invention may be used with equal success 1n hose-couplings of various types.

The principal object of this invention is to provide a novel means for quickly clamping two sections of hose together with a minimum amount of labor.

Another object, of the invention is to pro-` vide a clamping means for the purpose set forth which can be locked by the swinging of a lever in the op osite direction.

A further object oigthe invention is to pro-4 vide a coupling of the character described which is composed of a minimum number of parts, is therefore simple in construction, and is cheap to manufacture.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood thatvarions changes in the form, proportion, size and minor details of construction wit-hin the scope of the claims, may be resorted to without departing from the spirit or sacrificing;I any ot the advantages of the invention.

In the drawings: Figure l is a side eleva- 'tion of a hose coupler constructed in accordance with my invention7 the view showing the parts in their unlocked positions, Fig. 2 is a similar view but showing the parts in their locked positions, Fig. 3 is a longitudinal sectional view through the same, Fig. 4 is a sectional View taken on the line 1 4 of Fig. 2. Fig. 5 is a perspective view of the stop element. Figs. 6 and 7 are detail perspective views of certain shafts used herewith.

Like reference numerals designate corresponding parts in all the "figures .of the drawings.

Referringr to the drawings, 7 designates a normally vertical feed pipe havingl a lateral extension 8 at its lower end. The extreme end of this extension is formed with a conical head 9, constituting a male end, the small end thereof being located at the end of the extension. Adapted to be supported by a tender by any suitable means is a hose 10 having an enlarged connecting female end 11 of a shape corresponding to the head 9 and adapted to fit thereover, said end being provided with diametrically opposed pins 11a-11a. Disposed between the head 9 and the end and secured to the former, is a packing element 11b of rubber or any other suitable material.

Disposed around the extension 8 is a clamp 12 having athickened connecting portion 13-which rock shaft 15 'having reduced angular end portions 15-15 which project vbeyond the y extension 8 and threaded ends 16-16 Bellcrank levers 17-17 are respectively secured j' at their angles to the angular endportions 15-15 of said shaft, and nuts 17-17il are associated with the ends 16-16.

:Links 18-'18 are each pivotally connected at one end as at 19 to the end of the adjacent Adrm j of the lever 17, and has its other end formed with a plurality of vnotches 20 ada ted to 'enage the respective pin 11' of the iose 10.

isposed around the feed pipe 7 above the extension 8 is a clamp 21 having,r a thickened connecting portion 22 which is formed with an opening 23 extending transversely OEE the pipe 8 and disposed in a plane parallel to the rock shaft 15 before mentioned. Loosel mounted in the opening 23 is a rock'shafitI l 24 having reduced angular end port-ions S25-25 4which project beyond the pipe 7 and threaded ends 2-26.

A rocker 'arm 27 is securedY at one end to one end portion 25 of the shaft 24, and a V-shaped lever 28 is connected at, its angle' to the other end lportion 25 of said shaft.. One arm 29 of this lever constitutes a rocker arm and the otheri arm 30 a hand lever. A

link 31 is-pivotally connected at one end, asA

at 32, to the free end of the adjacent armfof the adjacent bell-crank lever 17 and at its l other end as at 33 to the free end of the rocker arm 29 of the lever 28. A second link 34 is pivotally connected at one end, as at 35, to the free end of the adjacent arm of the other bell-crank lever 1.7 and at its other end as at 3G to the free end oi the rocker arm 27. It will thus be observed that when the hand lever 30 is lifted, the shaft 24 is formed with an opening'- 14 extending transversely of said extenslon. Loosely mounted 1n said openlng 14 `1s a iaml ina' the couplingr Water tight.

ain-l1 will be rocked, and as a result, the arms 2'4" and 29 which are disposed in the same plane, will also be lifted, thereby simultaneously pulling on the links 3l and 3l and conse- 5 {juently swinging` the bell-crank levers 17-17. These levers, through the medium oi' the links 18-18, pull the connecting' end ll of the hose l0 around the head 9 of the extension 8, the packing' element 11b render- The hand lever 30 is swung until arms 27 and Q9 are beyond their center line, and in order` to prevent the lever 30 from further swinging, there is provided a stop element 37. This element has one end biiurcated to vform clampingl arms 38-38 which surround the pipe above the clamp 2l, and are secured by a bolt 39 or other suitable means. This element extends laterally above the extension 20 8 of the pipe 7, and terminates in a short arm 40y Which projects in the path oi movement ot' said hand lever 30 to form a stop therefor.

Secured to the head 9 oi the extension 8,

uand projectinginto the end ll ot' the hose 10 is a strainer 41 of any suitable construction.

What is claimed is:

l. ln combination With pipe sections respectively including male and female ends, a

bell-crank lever fulcrumed upon one oi the sections, a link pivotally connected at one end to one arm of the lever and at its other end to the end of the other section, a rock shaft supported by the first mentioned section, a rocker arm projecting from said shait, a link connect-ing theother arm of the bell crank lever and the rocker arm, means to rotate said shaft to draw the ends of 'the sections together, other means to limit the movement of the last mentioned means in one direction supported on the first mentioned section, and means to hold the limit intr, means in adjusted position on said section and thereby vary the movement of the lirst mentioned means.

Q. in combination with pipe sections respectively including male and female ends, a bellcrank lever fulcrumed upon one of the 30 sections, a link pivotally connected at one shaft, a link connecting the other arm of the bell crank lever and the rocker arm, a

rot/daze hand lever connected to said shaft to rotate therewith, a stop elementcarried by said first mentioned section to limit the movenient in one direction of said hand lever and Ineens to secure said stop element in adjusted position on its section whereby the movement of said hand lever may be varied.

3. In combination with pipesections respectively includingmale and female ends, spaced clamps carried by one of said sections, a bell-crank lever 'ulcrumed at its an- ,ele upon one of the clamps, a link pivotally connected at one end to one arm of the lever and provided at its other end with spaced hooks, lugs carried by the end of the other section .for selective engagement by said hooks, a rock shaft supported by the other clamp, a rocker arm projecting* from said shaft, a link connecting' the other arm of the bell crank lever and the rocker arm, a hand lever iixed to said shaft, a clamp mounted on the first mentioned section and movable to and from said shaft, bolts extendirui,F through said clamp to hold the "same in adjusted position on the section, and a stop arm extending from said last mentioned clamp and lying' in the path of said lever.

et. In combination with pipe sections respectively includingr male and female ends, spaced clamps carried by one ot' said sections, each clamp including a thickened connecting; portion having an openingr formed therein and disposed transversely of said sections, rock shafts respectively mounted in the openings of said clamps, a bell-crank lcver iixedly secured at its angle to each end of one of the rock shafts, links respectively pivotally connected at one end to one arm of each lever and at the other end to the end of the other section, a rock arm connected to each end ot the other rock shaft, links respectively connecting the other arms of the bell crank levers and the rocker arms, a lever connected to the last mentioned shaft to rotate therewith, a stop element carried by said first mentioned section to limit the movement in one direction of said lever and means to rock said stop element in adjusted position in its section.
